Dahlin, Jayme L. published the artcilePAINS in the Assay: Chemical Mechanisms of Assay Interference and Promiscuous Enzymatic Inhibition Observed during a Sulfhydryl-Scavenging HTS, COA of Formula: C18H14BrNO5S2, the publication is Journal of Medicinal Chemistry (2015), 58(5), 2091-2113, database is CAplus and MEDLINE.
Significant resources in early drug discovery are spent unknowingly pursuing artifacts and promiscuous bioactive compounds, while understanding the chem. basis for these adverse behaviors often goes unexplored in pursuit of lead compounds Nearly all the hits from our recent sulfhydryl-scavenging high-throughput screen (HTS) targeting the histone acetyltransferase Rtt109 were such compounds Herein, we characterize the chem. basis for assay interference and promiscuous enzymic inhibition for several prominent chemotypes identified by this HTS, including some pan-assay interference compounds (PAINS). Protein mass spectrometry and ALARM NMR confirmed these compounds react covalently with cysteines on multiple proteins. Unfortunately, compounds containing these chemotypes have been published as screening actives in reputable journals and even touted as chem. probes or preclin. candidates. Our detailed characterization and identification of such thiol-reactive chemotypes should accelerate triage of nuisance compounds, guide screening library design, and prevent follow-up on undesirable chem. matter.
